  • Hands-on experience building modern web applications with React, including knowledge of performance tuning and component design
  • Backend development experience in a production environment using Go (or similar languages), especially in support of fullstack feature development
  • A track record of collaborating cross-functionally to scope projects, meet deadlines, and deliver solutions that directly impact product adoption and customer satisfaction
